Product Description
Product Overview
The MMKP82 series is a boxed, double-sided metallized polypropylene film capacitor designed for absorption, resonance, and high-frequency DC and pulse applications in electronic equipment. These capacitors feature a non-inductive winding structure with a metallized polyester film and metallized polypropylene film composite. They are encapsulated in a flame-retardant plastic case and epoxy resin, ensuring good dimensional consistency and low loss with minimal internal heating. Typical applications include switching power supplies, electronic ballasts, motor control, and TV vertical deflection circuits.

Usage Rules
- Operating Range: Do not exceed the upper category temperature. Avoid overload. Do not exceed maximum pulse current.
- Handling Precautions: Avoid repeated squeezing at the lead root. Be cautious of lead tip sharpness.
- Soldering: Solder heat can transfer to the capacitor core. Be mindful of potential attenuation or damage from high temperature and prolonged soldering.
- Wave Soldering: TP110 for 120s; Ts120 for 45s. For P7.5mm, T4mm: Soldering time < 4 seconds.
- Soldering Iron: Tip temperature not exceeding 350, time not exceeding 3 seconds.
- Note: Lead-type film capacitors are not suitable for reflow soldering. Ts: Maximum temperature the capacitor body can withstand during wave soldering. Tp: Maximum preheating temperature the capacitor body can withstand.
